INSTALLATION RECOMMENDATIONS

• It is prohibited to connect this device to the same electrical cables without appropriate network filters, to which

other high-power devices are connected.

• Do not route signal cables near or with energy and power cables.

• Keep a distance of remotely operated devices, avoid high-power overload, avoid device contact with group or phase

control devices, as well as other devices, which may interfere the operation of boiler’s regulator.

• When connecting the device, remember that the building system must be equipped with the connector and automatic

connector. This element has to be close to the controller, easily accessible by the user and marked in a way it would

be clear that it is for the switching off the device.

• The manufacturer is not responsible for damages caused by failure to comply with these instructions.

PURPOSE VAL-01 controller is an innovative microprocessor device, which regulates the work of solid fuel boiler Stropuva. The

application of the control device and complex algorithms ensures easy use and automation of the combustion process. This

control device is adapted for work with the central heating pump. This controller also has a possibility to connect with the

room thermostat (not included in the kit), with the help of which you can change the operating parameters of the boiler,

when the temperature of the premises reaches a certain temperature. Depending on the purchased room thermostat, you can

program hourly, daily, weekly, etc. modes.

OPERATING PRINCIPLE

The device works on the principle of oxygen dosing. Oxygen is supplied through the fan and dosed by regulating the opening

angle of the air shutter with the help of electric gear. In this way, combustion process is being controlled. When the hot

water reaches the set temperature, the controller simply starts to maintain the temperature and depending on external

parameters can top the combustion process from 10 minutes to 5 hours. After disconnection, fuel is ignited automatically

with the help of blowing ventilator, which is connected to this controller. Boiler’s work can also be regulated with the room

thermostat. In this way, it is possible to regulate heating according to the current room temperature. The controller is

equipped with an automatic system (which detects the temperature sensor failure) and boiler controlling equipment, which

protect the central heating system.

CONTROL PANEL

Pause switcher:

0 – 10 min 1 – 30 min 2 – 60 min 3 – 90 min 4 – 120 min 5 – 180 min 6 – 240 min 7 – 300 min

Switcher of fuel types:

0 – wood: 1 – carbon 2 – peat briquettes 3 – wood sawdust briquettes 4 – wood sawdust granules

Operating modes of the indicator: Blue color lights – STOP mode. Air supply shutter is closed; ventilator does not work. In this mode, you can load the boiler with fuel and start it up.

Red color lights – initial control. After starting up the boiler and fuel burning well, you have to unhook the ring of the line (lower air distributor on the fuel), press start/stop button START/STOP, wait 10-15 seconds until air supply shutter opens and close the door. Red indicator will light up – initial control. The initial fuel ignition phase is in this mode.

Red/green/blue color flashes – the main control. This mode will be activated, if boiler’s operating temperature will not reach 70 degrees or due to termination and restoration of power supply to the controller.

Blue/red color flashes – no power. The controller is equipped with a reserve accumulator, so in case of power failure, air supply shutter will close automatically.

Green color lights – conditioning before the pause. The boiler is extinguished gradually by limiting the air supply. This mode will be activated when temperature in the boiler will reach 80 degrees or when premises will be warm enough and room thermostat will be activated.

Red color flashes - pause. This is boiler’s standby mode, during which the air supply to the boiler is completely limited and the circulation pump is turned off. The boiler is extinct for a specified period of time or until room thermostat will give a signal to heat the house and at the end of a specified timeout period. After pause, the initial control mode turns on and the process is repeated.

Red/green flashes – 6 h pause. Fuel clean out turns on at longer than 6 hours pause.

Blue flashes –burning out of coals. When fuel burns out and boiler’s temperature reaches 35 degrees, then coals burning mode turns on, during which air is blown into the boiler to the maximum. After coals burning out the boiler switches to STOP mode.

Blue/green flashes – problem with sensor. It is prohibited to burn the boiler at this mode. You need to check connection contacts of the temperature sensor and to fix the connection or contact the service department.

INSTALLATION

Fig. 1 Unscrew thermal regulator of the boiler “STROPUVA” and remove the air shutter.

Fig. 2 Place the rubber seal on air preheating chamber

Fig. 3 Place the holder inside the boiler

Fig 4. Screw the air supply channel to the top of the boiler

Fig. 5 Attach the armor

Fig. 6 Attach temperature sensor to the supply from the boiler

Fig. 7 Attach temperature sensor with adhesive foil

Fig. 8 Connect the central heating pump

Fig. 9 Turn into the grid power Nr. 1 and power Nr. 2. You can use the controller without room thermostat – in such way 8-9 contacts are connected with a connector. If you use the controller with room thermostat – then remove the connector and increase the length of wires up to room thermostat installed in premises.

USE OF CONTROL DEVICE

Make sure that controller is turned on and light diode lights in blue – Stop mode. Before starting up the boiler, set the type of fuel and pause duration. Pause – is time, when the boiler is not burning and is on a standby mode. If you use the controller without room thermostat – we recommend choosing pause duration depending on outside temperature. If it is warm outside – you can choose a longer pause duration, if cold – shorter. Pause duration depends on the heated area and if external thermostat is turned on. If you use it, then the controller automatically selects the length of the pause.

Start burning the top of the fuel load, slightly closing the door leaving a gap of 2-5 cm. When fuel starts burning, remove the ring with the lifting line from the hook and press the start button (light diode lights in red - initial control). Wait 10-15 seconds and close the door.

When fuel burns out completely the controller will automatically switch to Stop mode. The controller is equipped with a reserve accumulator, so in case of power failure, air supply shutter will close and

light diode will signal red and blue lights. When power comes back – the boiler will continue its work. When burning wood, we recommend putting wood sawdust briquettes intermittently in the middle of the fuel load.

In this way, at a longer pause – the boiler will easily start burning and continue its work.
